Ok, I hate putting people in my friends list to keep track of the @#*@#$&^ that jack up my group experience, so I was seeing if I could start doing my own Mod.

Here's what it does:
- You can add people that you group with and rate from 1 low - 5 high stars.
- Add comments if you want
- Keeps track of the times you group/first & last time you grouped with
- Alerts you if you are in a group/raid with someone that you have rated (ranking and reason if applicable)
- Upload? (Leads to collective information on player rating & collective comments)

This looks like an old thread but I think Karma does most of those features - I got bored of it myself, could never be bothered rating people, plus it doesn't allow for a way to separate guildmates and friends from everyone else, but it's not bad overall. The original isn't being updated but look for Karma Resurrected (or Resurrection, can't remember exactly) and it should work ok._________________EU-Draenor:
